#
# SYNOPSIS
#
#   AC_CHECK_RQRD_CLASS
#
# DESCRIPTION
#
#   AC_CHECK_RQRD_CLASS tests the existence of a given Java class,
#   either in a jar or in a '.class' file and fails if it doesn't
#   exist. Its success or failure can depend on a proper setting of the
#   CLASSPATH env. variable.
#
#   Note: This is part of the set of autoconf M4 macros for Java
#   programs. It is VERY IMPORTANT that you download the whole set,
#   some macros depend on other. Unfortunately, the autoconf archive
#   does not support the concept of set of macros, so I had to break it
#   for submission. The general documentation, as well as the sample
#   configure.in, is included in the AC_PROG_JAVA macro.
